A gunshot wound (GSW) is physical trauma caused by a projectile from a firearm. Damage may include bleeding, broken bones, organ damage, infection of the wound, or loss of the ability to move part of the body. Damage depends on the part of the body hit, the path the bullet follows through the body, and the type and speed of the bullet. Long-term complications can include lead poisoning and post-traumatic stress disorder (PTSD).
